Capacitor

Cybertechnomagical girl who needs some backstory if her player isn't too lazy. For starters, she's a bit of a wild child. Fight the system, anarchy forever and all that. Probably her cybertechnomagical powers come from something she stole from a nasty megacorporation. Let's say DarkLight Corp, because I like tie-ins to my other nonsense little worlds. Second, she lost her tail. Probably in the aforementioned stealing of whatever her power stems from. So she did what any rational cybergenius would do when faced with the situation: Use her new powers to construct a new one. So she's got a cybermechatail that probably has more features than a sonic screwdriver. Granted it doesn't even vaguely resemble a fox tail, but she doesn't care. If anyone makes fun of it she can just deploy the plasma scythe function and see how much they make fun of it. Why does she look hungry? Let's go with "Her powers stem from cybertechnomagical symbiotic nanobot swarm that she controls but they require hella power, which they can take from the hydrocarbons in food. So she eats a lot. Is probably guilty of eating at least one person, but they either deserved it or wanted it and paid her a lot of money. Who is she to deny wealthy crazy people? And the baton? Well, sometimes it's not worth unleashing her unspeakably overpowered powers upon someone and it's better to just thwack them about the kneecap until they bugger off or fall over screaming. But really, she's a nice girl. And she's probably more likely to eat your bank account or your smartphone than you. Hydrocarbons are everywhere, but rare metals and silicates not so much.
